Calls have been made to the Justice Minister to tackle anti-social behaviour at the Forty Foot at Sandycove Beach, after a young couple was spotted allegedly having sex on top of a shed.
And a local councillor has called for more garda resources to police the area, saying anti-social problems are a "seasonal issue".
Dun Laoghaire TD Richard Boyd Barrett has called on Charlie Flanagan to make a plan to tackle anti-social behaviour in the area.
He accused a small minority of ruining the experience for everyone who flocks to the hugely popular public sun spot when there is good weather.
Reports of binge drinking have also led to "unpleasant" experiences for families, claims local councillor Cormac Devlin.
Speaking to Dublin Live, Councillor Devlin said: "It's a seasonal issue, around the summer time. It's all about the weather.
"It's a public amenity, and it doesn't take much to ruin it. The drinking is all ages, but there's a bye-law about drinking in public.
"People have different tolerances to anti-social behaviour, but it can be very disruptive and intimidating when people are drinking and shouting around families."
Councillor Devlin said a garda presence would make people act in an "orderly manner" and help to curtail the anti-social behaviour.
He continued: "It all comes down to garda resources. The area needs to be better resourced and people need to see a better presence.
"That comes back to anti-social behaviour. People having sex, that's unpleasant for people down there with families.
"Many incidents that have been reported, they've been very varied. Again, it all comes down to garda resources.
"If the guards are there, people will act in an orderly manner."
